DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary sill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

FIG. 1 illustrates a GUI and an avatar, which are displayed in an AR according to an embodiment of the disclosure.

Referring to FIG. 1, in a real space 10, an AR device 101 may be worn on a part (e.g., a head) of a body of a user 50. The AR device 101 may refer to a device including a display capable of supporting an AR. For example, the AR device 101 may include at least one of a wearable device and a head mounted display (HMD).

According to an embodiment of the disclosure, the AR device 101 may output a first GUI 30 for displaying a contact stored in a message application or a contact application of a user device (e.g., a smartphone, not illustrated) in 3 dimensional (3D) in an AR 20. For example, the first GUI 30 may be referred to as a ‘nest’.

According to an embodiment of the disclosure, the first GUI 30 may be fixed in a specified area of the real space 10. For example, when a user input for placing the first GUI 30 on a table 12 of the real space 10 is received, the AR device 101 may display the first GUI 30 on the table 12. In this case, even though the AR device 101 moves by a movement of the user 50, a location of the first GUI 30 may not be changed in the real space 10. According to another embodiment of the disclosure, the first GUI 30 may be fixed to a specified location of an area (e.g., a viewing area 1510 of FIG. 15A) that the user 50 is capable of viewing through the AR device 101. In this case, when the AR device 101 moves by the movement of the user 50, the first GUI 30 may move together with the movement of the AR device 101.

The first GUI 30 may include at least one avatar (e.g., 32, 34, or 36) corresponding to each contact stored in the user device. In this specification, it may be described that the first GUI 30 ‘includes’ an avatar. However, according to various embodiments of the disclosure, the avatars 32, 34, and 36 in the AR 20 may be positioned at various locations adjacent to the first GUI 30. For example, referring to an enlarged view 22 in which the AR 20 is enlarged, the avatars 32, 34, and 36 may be disposed on the first GUI 30. As another example, although not illustrated in FIG. 1, the avatars 32, 34, and 36 may be disposed below, side, or inside the first GUI 30.

The avatars 32, 34, and 36 may represent contacts stored in the user device, respectively. According to embodiments of the disclosure, a user of the user device (or the AR device 101) may select one of template avatars that have been stored in advance, and thus an appearance of the avatars 32, 34, and 36 may be determined, an appearance of the avatars 32, 34, and 36 may be arbitrarily determined based on information (e.g., an age, a gender, or a country) included in contact information. Alternatively, an appearance of the avatars 32, 34, and 36 may be determined based on settings of a counterpart.

A size of the AR space 20 capable of being provided by the AR device 101 is restricted as compared to the number of contacts stored in the user device, and thus the AR device 101 according to an embodiment may display only an avatar corresponding to at least one pre-selected contact among contacts stored in the user device. For example, the AR device 101 may display, on the first GUI 30, a contact (e.g., “favorite”) selected by user settings or a contact having a high frequency of communication.

FIG. 2 illustrates a block diagram illustrating an electronic device in a network environment 200 according to an embodiment of the disclosure.

For example, when the electronic device 201 includes the main processor 221 and the auxiliary processor 223, the auxiliary processor 223 may be adapted to consume less power than the main processor 221, or to be specific to a specified function. The auxiliary processor 223 may be implemented as separate from, or as part of the main processor 221.

The auxiliary processor 223 may control at least some of functions or states related to at least one component (e.g., the display module 260, the sensor module 276, or the communication module 290) among the components of the electronic device 201, instead of the main processor 221 while the main processor 221 is in an inactive (e.g., a sleep) state, or together with the main processor 221 while the main processor 221 is in an active state (e.g., executing an application). According to an embodiment of the disclosure, the auxiliary processor 223 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module 280 or the communication module 290) functionally related to the auxiliary processor 223. According to an embodiment of the disclosure, the auxiliary processor 223 (e.g., the neural processing unit) may include a hardware structure specified for artificial intelligence model processing.

According to an embodiment of the disclosure, the display module 260 may include a touch sensor adapted to detect a touch, or a pressure sensor adapted to measure the intensity of force incurred by the touch.

The audio module 270 may convert a sound into an electrical signal and vice versa. According to an embodiment of the disclosure, the audio module 270 may obtain the sound via the input module 250, or output the sound via the sound output module 255 or a headphone of an external electronic device (e.g., the external electronic device 202) directly (e.g., wiredly) or wirelessly coupled with the electronic device 201.

The sensor module 276 may detect an operational state (e.g., power or temperature) of the electronic device 201 or an environmental state (e.g., a state of a user) external to the electronic device 201, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment of the disclosure, the sensor module 276 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The interface 277 may support one or more specified protocols to be used for the electronic device 201 to be coupled with the external electronic device (e.g., the external electronic device 202) directly (e.g., wiredly) or wirelessly. According to an embodiment of the disclosure, the interface 277 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

The communication module 290 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 201 and the external electronic device (e.g., the external electronic device 202, the external electronic device 204, or the server 208) and performing communication via the established communication channel. The communication module 290 may include one or more communication processors that are operable independently from the processor 220 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment of the disclosure, the communication module 290 may include a wireless communication module 292 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 294 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 298 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 299 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 292 may identify and authenticate the electronic device 201 in a communication network, such as the first network 298 or the second network 299, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 296.

The wireless communication module 292 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 292 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 292 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 292 may support various requirements specified in the electronic device 201, an external electronic device (e.g., the external electronic device 204), or a network system (e.g., the second network 299). According to an embodiment of the disclosure, the wireless communication module 292 may support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of 1 ms or less) for implementing URLLC.

In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 298 or the second network 299, may be selected, for example, by the communication module 290 (e.g., the wireless communication module 292) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 290 and the external electronic device via the selected at least one antenna. According to an embodiment of the disclosure, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 297.

According to various embodiments of the disclosure, the antenna module 297 may form an mmWave antenna module. According to an embodiment of the disclosure, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment of the disclosure, commands or data may be transmitted or received between the electronic device 201 and the external electronic device 204 via the server 208 coupled with the second network 299. Each of the external electronic devices 202 or 204 may be a device of a same type as, or a different type, from the electronic device 201. According to an embodiment of the disclosure, all or some of operations to be executed at the electronic device 201 may be executed at one or more of the external electronic devices 202, 204, or 208. For example, if the electronic device 201 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 201, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 201. The electronic device 201 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device 201 may provide ultra-low-latency services using, e.g., distributed computing or mobile edge computing. In another embodiment of the disclosure, the external electronic device 204 may include an internet-of-things (IoT) device. The server 208 may be an intelligent server using machine learning and/or a neural network. According to an embodiment of the disclosure, the external electronic device 204 or the server 208 may be included in the second network 299. The electronic device 201 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

The electronic device 201 illustrated in FIG. 2 may be the AR device 101 of FIG. 1 or a device (e.g., a user device) that is electrically connected to the AR device 101 and stores contacts.

FIG. 3 illustrates a block diagram of a user device according to an embodiment of the disclosure.

An AR device 302 may be implemented as a wearable device (e.g., a HMD) capable of being worn by a user. The AR device 302 may include a display for providing an AR when the user device 301 operates in an AR mode. For example, when the user device 301 is mounted on the AR device 302, the user device 301 may execute the AR mode. As another example, when the user device 301 is not mounted on the AR device 302, the user device 301 may execute the AR mode depending on user settings or execution of an application associated with the AR mode. When the AR mode is executed, the user device 301 may three-dimensionally render a GUI (e.g., the first GUI 30 and the avatars 32, 34, and 36 of FIG. 1) displayed in the AR through the AR device 302. In this case, two screens corresponding to the user's eyes (e.g., a left eye and a right eye) may be output through a display of the AR device 302.

The user device 301 may include a touch screen 320, a controller 330, a memory 340, and a communication circuit 350. As another example, the user device 301 may further include at least one of other components included in the electronic device 201 of FIG. 2.

As another example, the touch screen 320 may include only the display panel 321 without including the touch panel 322.

The controller 330 may perform a function that is identical or similar to the function of the processor 220 of FIG. 2. The controller 330 may include an AR mode processing module 331, an event detection module 332, an event information processing module 333, and an application controller 334. Modules included in the controller 330 may mean configurations implemented by hardware or software. When implemented in software, the modules included in the controller 330 may be stored in the memory 340 as an instruction set. The controller 330 may perform operations of the user device 301 by executing the instruction set.

When the user device 301 operates in the AR mode, the AR mode processing module 331 may process operations associated with the AR mode. For example, the AR mode processing module 331 may load at least one AR program 341 stored in the memory 340.

The event detection module 332 may detect an event that occurs when the AR mode is operated. The event detection module 332 may determine whether there is information to be displayed on a screen associated with an event occurring when the AR mode is operated. For example, when content, such as a message is received from a counterpart's electronic device through a message application, the event detection module 332 may detect that an event occurs.

The event information processing module 333 may process information that is to be detected by the event detection module 332 and is to be displayed in an AR. For example, the event information processing module 333 may convert information (e.g., a text message) associated with a detected event into a 3D image to be displayed in the AR. In this case, the event information processing module 333 may convert two-dimensional (2D) information into information corresponding to left and right eyes, may synthesize the converted information, and may render the synthesized information to be displayed on the AR device 302.

The application controller 334 may control an application when the user device 301 operates in the AR mode. For example, when a message application is executed in the AR mode, the application controller 334 may block other applications or operate other applications in the background such that other applications do not interfere with execution of the message application.

The memory 340 may perform a function that is identical or similar to the function of the memory 230 of FIG. 2. The memory 340 may store the AR program 341 and event-related information 342. The AR program 341 may be an application associated with an AR mode operation of the user device 301. The event-related information 342 may include information associated with an event occurring in the AR.

The communication circuit 350 may perform a function that is identical or similar to the function of the communication module 190 of FIG. 2. The communication circuit 350 may be used to be electrically connected to the AR device 302 or an external server. For example, the communication circuit 350 may be connected to the AR device 302 through Bluetooth, Wi-Fi, or tethering. As another example, the communication circuit 350 may include a wired interface.

FIG. 4 is a block diagram of a program module according to an embodiment of the disclosure.

Referring to FIG. 4, a program module 400 may include a configuration that is identical or similar to that of the program 240 of FIG. 2. The program module 400 may include a system operating system (e.g., an operating system (OS)) 410, a framework 420, and an application 430.

The system operating system 410 may perform a function that is identical or similar to the function of the operating system 242 of FIG. 2. The system operating system 410 may include at least one system resource manager or at least one device driver. The system resource manager may control, allocate, or recover a system resource. The system resource manager may include at least one manager, such as a process manager, a memory manager, or a file system manager. The device driver may include at least one driver, such as a display driver, a camera driver, a Bluetooth driver, a shared memory driver, an USB driver, a keypad driver, a Wi-Fi driver, an audio driver, or an inter-process communication (IPC) driver.

For example, the framework 420 may include the middleware 244 of FIG. 2. The framework 420 may provide a function necessary for an application through an application programming interface (API) such that the application is capable of efficiently using limited system resources in an electronic device (e.g., the user device 301 in FIG. 3). When the electronic device operates in an AR mode, the framework 420 may control a function associated with the AR mode. For example, the framework 420 may control at least one AR application (e.g., a plurality of AR applications 451).

The application 430 may perform a function that is identical or similar to the function of the application 246 of FIG. 2. The application 430 may include a plurality of AR applications (e.g., the plurality of AR applications 451) and a plurality of general applications (e.g., 452). The AR application may refer to an application that operates in the AR mode, and, the general application may refer to an application that operates in a normal mode, not the AR mode.

According to an embodiment of the disclosure, the application 430 may further include an AR control application 440. At least one AR application and/or at least one general application 450 may be controlled by the AR control application 440. For example, the AR control application 440 may perform a function that is identical or similar to the function of at least one of the AR mode processing module 331, the event detection module 332, the event information processing module 333, or the application controller 334 of FIG. 3.

According to an embodiment of the disclosure, when a user device operates in the AR mode or the normal mode, the system operating system 410 may notify the framework 420 that an event occurs (e.g., receiving a text message from a counterpart's electronic device). When an event occurs in the case where the user device operates in the normal mode, the framework 420 may control execution of the general application such that a screen associated with the event is displayed through a display (e.g., the touch screen 320 in FIG. 3) of the user device. When an event occurs in the case where the user device operates in the AR mode, the framework 420 may control the general application such that a screen associated with the event is displayed only through an AR device (e.g., the AR device 302 in FIG. 3) and is not displayed through a display of the user device, thereby preventing unnecessary resource consumption and preventing the general application from interfering with an operation in the AR mode. According to another embodiment of the disclosure, when an event occurs in the case where the user device operates in the AR mode, the framework 420 may provide an environment in which a user is capable of controlling an AR device through the user device, by controlling an event-related screen to be displayed through the display of the user device as well as the AR device.

The memory 520 may store a spatial map 521. For example, the spatial map 521 may refer to spatial information about a real space (e.g., the real space 10 of FIG. 1) surrounding the AR device 501. For example, when the AR device 501 is worn by a user, the AR device 501 may generate a space surrounding the AR device 501 as a 3D map by scanning a surrounding area through the sensor 550. The AR device 501 may identify a location of the AR device 501 by using the generated spatial map 521 or may identify a location where a specific GUI (e.g., the first GUI 30 of FIG. 1 or the avatars 32, 34, and 36) is positioned.

The memory 520 may include an API 522 for providing a necessary function to applications stored in the AR device 501.

The input/output interface 530 may include a hardware or software configuration for interfacing with a user. For example, the input/output interface 530 may include a microphone or a speaker.

The communication interface 540 may be configured to be connected to a user device (e.g., the user device 301 in FIG. 3) by wire or wirelessly. The communication interface 540 may also be referred to as a “communication module” or a “communication circuit”.

The sensor 550 may include at least one sensor. For example, the sensor 550 may include at least one of a hand pose sensor 551 capable of sensing a movement of the user's hand (or a finger), a head pose sensor 552 capable of sensing a movement of the user's head, or another sensor 553. For example, the other sensor 553 may include at least one of a location measurement sensor capable of identifying a location of the AR device 501 in a real space, such as a global positioning system (GPS), a motion sensor capable of sensing a direction or movement of the AR device 501, such as an acceleration sensor, a geomagnetic sensor, and a gyro sensor, a proximity sensor capable of sensing an external object positioned at a location close to the AR device 501, a red green blue (RGB) sensor capable of sensing an intensity of light or color around the AR device 501, an illuminance sensor, or a hall sensor.

The display 560 may include a see-through display 565 to provide an AR to a user.

The processor 570 may be operatively connected to the memory 520, the input/output interface 530, the communication interface 540, the sensor 550, and the display 560, and may perform overall operations of the AR device 501.

FIG. 6 is a diagram of a message application 630 combined with a hardware configuration of an AR system according to an embodiment of the disclosure.

Referring to FIG. 6, an AR device 610 and a user device 620 may be electrically connected to each other. For example, the user device 620 may be mounted in the AR device 610, the AR device 610 and the user device 620 may be connected through a wired interface. Alternatively, the AR device 610 and the user device 620 may be connected via wireless communication. A processor 612 and a memory 614 of the AR device 610 may perform functions that are identical or similar to functions of the processor 570 and the memory 520 of FIG. 5, respectively. A processor 622 and a memory 624 of the user device 620 may perform functions that are identical or similar to functions of the controller 330 and the memory 340 of FIG. 3, respectively.

The message application 630 may be stored in the memory 624 of the user device 620. In this case, the message application 630 may perform functions that are identical or similar to those of the modules included in the controller 330 of FIG. 3 or the AR control application 440 of FIG. 4. For example, the message application 630 may render at least one avatar 632 (e.g., the avatar 32, 34, or 36 of FIG. 1) and a first GUI 634 (e.g., the first GUI 30 of FIG. 1) that are to be displayed through a see-through display 640 (e.g., the display 560 of FIG. 5) of the AR device 610, and may transmit the rendered first GUI 634 and the rendered at least one avatar 632 to the AR device 610. When a user input 635 to select one of at least one avatar included in the first GUI 634 is received, the message application 630 may render a second GUI 638 and a selected avatar 636 such that the selected avatar 636 is displayed on the second GUI 638 (e.g., a second GUI 920 in FIG. 9) indicating a message thread. The message application 630 may transmit the rendered second GUI 638 and the selected avatar 636 to the AR device 610. While the second GUI 638 is displayed, the message application 630 may receive a user input 650 to enter content. For example, the content may include at least one of a text, an image, 3D content, or a voice.

The AR device 610 may output the first GUI 634, at least one avatar 632, the selected avatar 636, and the second GUI 638, which are rendered through the message application 630, through the see-through display 640. According to an embodiment of the disclosure, the AR device 610 may obtain the user input 635 to select an avatar and the user input 650 to enter content, through a sensor (e.g., the sensor 550 in FIG. 5).

FIG. 7 illustrates an operation flowchart 700 of an AR system for displaying a first GUI and an avatar according to an embodiment of the disclosure. An AR system may refer to a system including an AR device (e.g., the AR device 610 of FIG. 6) and a user device (e.g., the user device 620 of FIG. 6).

Referring to FIG. 7, in operation 710, the AR system may establish a connection between the AR device and the user device. The connection between the AR device and the user device may be established by wire or wirelessly. For example, when the AR device is implemented with an HMD, the user device may be mounted in the AR device. As another example, the AR device and the user device may be tethered through a wired interface or a wireless communication protocol (e.g., Bluetooth or Wi-Fi).

In operation 720, the AR system may detect that a message application of the user device is executed while the connection between the AR device and the user device is established. For example, the message application may include an application capable of communicating with another user device. For example, the message application may be replaced with a chat application, a video call application, a mail application, or a social network service (SNS) application.

In operation 730, the AR system may display a first GUI (e.g., GUI 30 of FIG. 1) including at least one avatar (e.g., the avatar 32, 34, or 36 of FIG. 1) in an AR. The first GUI may refer to an object in which a space in which at least one avatar is positioned is visually displayed in the AR. The at least one avatar may be based on at least one contact stored in the executed message application or a contact application linked to the message application.

FIG. 8A illustrates a first GUI including an avatar according to an embodiment of the disclosure.

Referring to FIG. 8A, an AR device may display a first GUI 820 in an AR. A shape of the first GUI 820 is not limited to an example shown in FIG. 8A, and, a shape of the first GUI 820 may be changed by user settings. The first GUI 820 may be fixed to a specified location in a real space or may be fixed to a specified area of a display of an AR device. According to an embodiment of the disclosure, the AR device may display at least one avatar 801, 802, or 803 at a location (e.g., a top surface of the first GUI) adjacent to the first GUI 820. The AR device may display the specified number of avatars on the first GUI 820 based on a size of the first GUI 820. For example, the AR device may display, on the first GUI 820, a contact, which is specified as a favorite depending on user settings, or a contact having a high frequency of contact.

According to an embodiment of the disclosure, the AR device may display icons 822, 824, and 826 of a menu for controlling the first GUI 820 or the at least one avatar 801, 802, or 803 at a location adjacent to the first GUI 820. For example, the menu corresponding to the icons 822, 824, and 826 may include at least one of editing of the first GUI 820, favorite settings, editing of an avatar, checking of recent communication, or editing of a contact.

FIG. 8B illustrates an avatar corresponding to a contact according to an embodiment of the disclosure.

For example, when an avatar of a contact stored in a user device has not been generated yet, the AR device may apply one of the pre-stored template avatars to a contact by a user's selection. When a counterpart of a contact, to which a template avatar is applied, generates a new avatar, an avatar stored in the user device may be changed from the template avatar to an avatar generated by the counterpart.

FIG. 9 illustrates a graphic effect of moving an avatar from a first GUI to a second GUI in an AR according to an embodiment of the disclosure.

Referring to FIG. 9, an AR device (e.g., the AR device 610 of FIG. 6) may display a second GUI 920 in an AR in addition to a first GUI 910. The first GUI 910 may correspond to the first GUI 30 of FIG. 1 or the first GUI 820 of FIG. 8A. The second GUI 920 may indicate a message thread of a message application. The second GUI 920 may be referred to as a ‘nest’. In this case, the first GUI 910 and the second GUI 920 may be referred to as a ‘main nest’ and a ‘secondary nest’, respectively.

According to an embodiment of the disclosure, the second GUI 920 may include a first avatar 922 corresponding to a user account of an AR system. It may be described that the second GUI 920 ‘includes’ the first avatar 922. However, according to various embodiments of the disclosure, the AR device may place the first avatar 922 at a location (e.g., top, bottom, side, or inside) adjacent to the second GUI 920.

According to an embodiment of the disclosure, the AR device may detect a user gesture 955 of moving 950 a second avatar 911 to the second GUI 920 among avatars 911 and 912 included in the first GUI 910. For example, the AR device may detect a user gesture 955 of grabbing 950 the second avatar 911 from the first GUI 910 through a hand pose sensor (e.g., the hand pose sensor 551 in FIG. 5), and dropping the grabbed second avatar 911 on the second GUI 920. The AR device may provide a graphic effect of moving the second avatar 911 from the first GUI 910 to the second GUI 920 depending on the detected user gesture 955 in the AR. When the second avatar 911 is located on the second GUI 920, a user device electrically connected to the AR device may communicate with a counterpart of a contact corresponding to the second avatar 911.

According to an embodiment of the disclosure, the second GUI 920 may be displayed before the second avatar 911 is selected, the second avatar 911 may be displayed in response to detecting a user gesture 955 that deviates from the first GUI 910.

According to an embodiment of the disclosure, to provide a sense of reality, such as a talking between the first avatar 922 and the second avatar 911, an AR device may change locations and directions of the first avatar 922 and the second avatar 911. For example, the AR device may be arranged such that the first avatar 922 and the second avatar 911 stand while facing each other on opposite sides of the second GUI 920.

According to an embodiment of the disclosure, the AR device may display icons 925 and 926 of menus for controlling a message thread indicated by the second GUI 920 at a location adjacent to the second GUI 920. For example, the menu corresponding to the icons 925 and 926 may include at least one of a function to terminate the message thread, a function to share content (e.g., at least one of an image, a video, a link, a map, another person's contact, a music, a file, a voice message, or a schedule), or a function to send an emoticon.

According to an embodiment of the disclosure, the AR device may terminate communication with a counterpart of a contact indicated by the second avatar 911, in response to detecting a user gesture 955 of moving 950 the second avatar 911 from the second GUI 920 to the first GUI 910.

FIGS. 10A and 10B illustrate an operation of detecting a gesture for an avatar according to various embodiments of the disclosure. FIGS. 10A and 10B illustrate an operation of detecting a movement of a user's finger (or a hand) by using a hand pose sensor.

Referring to FIGS. 10A and 10B, in operation 1001, an AR device may detect that a user's finger 1050 moves toward an avatar 1012 disposed on a first GUI 1010 (e.g., the first GUI 910 in FIG. 9). The AR device may not only detect the movement of the user's finger 1050, but may also measure a distance 1015 between the user's finger 1050 and the avatar 1012.

When the distance 1015 between the user's finger 1050 and the avatar 1012 is less than a threshold value, the AR device may determine that the avatar 1012 is selected by the user. According to an embodiment of the disclosure, to notify the user that the distance 1015 between the user's finger 1050 and the avatar 1012 is getting closer, the AR device may provide a graphic effect indicating a gesture of the avatar 1012. For example, referring to operation 1004 of FIG. 10B, the AR device may provide a graphic effect in which the avatar 1012 raises a hand in a direction, in which the user's finger 1050 is located, in response to detecting that the distance 1065 between the user's finger 1050 and the avatar 1012 is less than the threshold value. According to an embodiment of the disclosure, to guide a location where the user's finger 1050 is capable of grabbing the avatar 1012, the AR device may output an additional graphic effect (e.g., light) on a hand raised by the avatar 1012. For another example, referring to FIG. 10B, in operation 1005, the AR device may provide a visual graphic effect 1080 (e.g., firecrackers or pollen) at a periphery of the avatar 1012 in response to an event that the user's finger 1050 touches a hand of the avatar 1012.

In operation 1002, the AR device may detect a gesture in which the user's finger 1050 grabs the avatar 1012. For example, when the user's finger 1050 touches the avatar 1012 or the distance between the user's finger 1050 and the avatar 1012 is less than the threshold value, the AR device may detect a movement in which the user's finger 1050 is closed. The AR device may provide a graphic effect in which the avatar 1012 deviates from the first GUI 1010, in response to detecting a gesture in which the user's finger 1050 grabs the avatar 1012. The AR device may provide a graphic effect in which the avatar 1012 moves together with the user's finger 1050 depending on the movement of the closed user's finger 1050.

In operation 1003, the AR device may display the avatar 1012 on a second GUI 1020 in response to detecting that the user's finger 1050 is opened or detecting that the avatar 1012 is located at a location adjacent to the second GUI 1020 (e.g., the second GUI 920 in FIG. 9). The second GUI 1020 may include an avatar 1022 (e.g., the first avatar 922 of FIG. 9) corresponding to a user account of the AR device.

FIG. 10A illustrates an embodiment in which the avatar 1012 moves from the first GUI 1010 to the second GUI 1020. However, the same principle may be applied to an embodiment in which the avatar 1012 moves from the second GUI 1020 to the first GUI 1010.

FIG. 11 is an operation flowchart 1100 of an AR system for providing a graphic effect in which an avatar moves according to an embodiment of the disclosure.

Referring to FIG. 11, in operation 1110, an AR system may display a second GUI (e.g., the second GUI 920 of FIG. 9) indicating a message thread in an AR. According to an embodiment of the disclosure, the second GUI may include an avatar (e.g., the first avatar 922 of FIG. 9) corresponding to a user account of the AR system.

In operation 1120, the AR system may detect a first gesture for an avatar (e.g., the second avatar 911 of FIG. 9) included in the first GUI (e.g., the first GUI 910 of FIG. 9). For example, the AR system may detect a movement, in which a user's finger moves to a location close to an avatar and the user's finger is closed toward the avatar, using a hand pose sensor. The AR system may detect a movement in which the user's finger moves from the first GUI to the second GUI while the user's finger is closed.

In operation 1130, the AR system may provide a graphic effect, in which the avatar moves from the first GUI to the second GUI, based on the detected first gesture.

According to another embodiment of the disclosure, the AR system may display the second GUI in the AR in response to detecting the first gesture in operation 1120. For example, when it is detected that the user's finger grabs the avatar, the AR system may display the second GUI.

FIG. 12 illustrates an operation of changing a message thread according to an embodiment of the disclosure.

Referring to FIG. 12, a user device may generate a plurality of message threads for counterparts of a plurality of contacts. An AR device may display a plurality of GUIs 1231, 1232, 1233, and 1234 indicating the plurality of message threads in an AR. For example, the AR device may display the plurality of GUIs 1231, 1232, 1233, and 1234 indicating the plurality of message threads at a location adjacent to a second GUI 1220 (e.g., the second GUI 920 of FIG. 9) generated between a first avatar 1221 and a second avatar 1222.

According to an embodiment of the disclosure, the AR device may select a current message thread among the plurality of message threads depending on a user input. For example, the AR device may select the current message thread among the plurality of message threads depending on a movement in which a user finger 1250 scrolls the plurality of GUIs 1231, 1232, 1233, and 1234 in a specified direction (e.g., 1255) or touches one of the plurality of GUIs 1231, 1232, 1233, and 1234.

FIGS. 13A and 13B illustrate a user interface for entering a message according to various embodiments of the disclosure.

Referring to FIG. 13A, an AR device may display a second GUI 1320 (e.g., the second GUI 920 of FIG. 9) including a first avatar 1321 (e.g., the first avatar 922 in FIG. 9) and a second avatar 1322 (e.g., the second avatar 911 in FIG. 9). The AR device may display, at a location adjacent to the second GUI 1320, icons 1331, 1332, and 1333 for selecting the type of a user input to be transmitted to a counterpart of a contact corresponding to the second avatar 1322 and an icon 1334 for transmitting a obtained user input to the counterpart of the contact corresponding to the second avatar 1322. For example, the type of an input indicated by the icons 1331, 1332, and 1333 may include a voice input, a text input, or a reaction input. For example, the reaction input may refer to a gesture that appears on the first avatar 1321.

Referring to FIG. 13B, for example, the AR device may receive a user's voice input 1341. The AR device may obtain the voice input 1341 through a microphone (e.g., the input/output interface 530 of FIG. 5) of the AR device. As another example, a user device connected to the AR device may obtain the voice input 1341 through a microphone (e.g., the input module 250 in FIG. 2) of the user device, and may transmit the obtained voice input 1341 to the AR device. As another example, the AR device may obtain a text input through a virtual keyboard 1342 displayed in an AR. In this case, the AR device may obtain a text input on the virtual keyboard 1342 by detecting a movement of a user's finger using a hand pose sensor. As another example, the AR device may obtain a text input through a virtual keyboard output on a touch screen of a user device 1343. As another example, although not shown in FIG. 13B, the AR device may obtain a text input through an input device (e.g., a Bluetooth keyboard) separately connected to the user device 1343.

According to an embodiment of the disclosure, the AR device may obtain a message input through a plurality of input means. For example, when an application of a user device is operated in an AR mode, the AR device may obtain a message input through the virtual keyboard 1342 displayed in the AR and, at the same time, may obtain a message input through the keyboard output on a touch screen of the user device 1343. According to another embodiment of the disclosure, the AR device may set a specific input means as a default means for obtaining a message input. According to another embodiment of the disclosure, the AR device may obtain a message input through an input means that is last used.

According to an embodiment of the disclosure, the AR device may transmit the obtained message (e.g., a voice or a text) indicated by a user input to a counterpart of a contact corresponding to the second avatar 1322.

According to an embodiment of the disclosure, the AR device may provide a sense of reality as if a user of the first avatar 1321 speaks directly to a user of the second avatar 1322, by displaying a text corresponding to the transmitted message or a speech bubble 1350 including a text on the first avatar 1321.

FIG. 14 illustrates a UI for displaying a message according to an embodiment of the disclosure.

Referring to FIG. 14, an AR device may display a second GUI 1420 (e.g., the second GUI 920 of FIG. 9) including a first avatar 1421 (e.g., the first avatar 922 in FIG. 9) and a second avatar 1422 (e.g., the second avatar 911 in FIG. 9). The AR device may display a message received from an electronic device of a counterpart or a message transmitted to the electronic device of the counterpart in an AR in various shapes.

For example, in operation 1401, the AR device may display a speech bubble 1431 including a text corresponding to a message in the AR. For example, the speech bubble 1431 may be displayed on an avatar (e.g., the first avatar 1421) corresponding to a subject (e.g., a user of the AR device) that sends a message. According to an embodiment of the disclosure, the AR device may control the speech bubble 1431 to disappear after a specified time.

For another example, in operation 1402, the AR device may display a UI 1432 indicating a voice message in the AR. When a user input for selecting the UI 1432 is received, the AR device may output a voice through a speaker (e.g., the input/output interface 530 of FIG. 5).

According to an embodiment of the disclosure, the AR device may output a message as a voice or a text depending on user settings. For example, even though the AR device obtains a voice message or a voice input, the AR device may display a text corresponding to a voice in the AR through a speech-to-text (STT) technology. On the other hand, even though the AR device obtains a text message or a text input, the AR device may output a voice corresponding to a text in the AR through a text-to-speech (TTS) technology.

For another example, in operation 1403, the AR device may display a UI 1433 indicating message transmission records in the AR. According to an embodiment of the disclosure, the UI 1433 may be scrolled in a specified direction (e.g., upward or downward) based on a user gesture. According to an embodiment of the disclosure, when a specified time elapses or the number of texts included in the UI 1433 is not less than a specified number, the AR device may reduce visual clutter by making at least part of texts included in the UI 1433 disappear from the AR.

FIG. 15A illustrates an operation of outputting a message depending on a viewing area according to various embodiments of the disclosure.

Referring to FIG. 15A, when an AR device 1505 (e.g., the AR device 610 in FIG. 6) is worn on a part (e.g., a head) of the body of a user 1550, an AR space that the user 1550 is capable of viewing may be limited due to a physical size limitation of a display (e.g., the display 560 of FIG. 5) of the AR device 1505. In this specification, an area that the user 1550 is capable of viewing through the AR device 1505 may be referred to as a ‘viewing area (e.g., the viewing area 1510)’. For example, when a second GUI 1520 (e.g., the second GUI 920 in FIG. 9) including a first avatar 1521 (e.g., the first avatar 922 in FIG. 9) and a second avatar 1522 (e.g., the second avatar 911 in FIG. 9) is fixed to a specified location in a real space, the second GUI 920 may be positioned within the viewing area 1510 or may deviate from the viewing area 1510, depending on a movement of the AR device 1505.

According to an embodiment of the disclosure, the AR device 1505 may output a message as a text or a voice based on whether the second GUI 1520 deviates from the viewing area 1510. For example, when the second GUI 1520 is located within the viewing area 1510 as shown in the left diagram of FIG. 15A, the AR device 1505 may output a message in a text form (e.g., 1525). As another example, when the second GUI 1520 deviates from the viewing area 151 as shown in the right diagram of FIG. 15A, the AR device 1505 may output a message as a voice.

FIG. 15B illustrates an operation flowchart 1500 of an AR device for outputting a message depending on a viewing area according to an embodiment of the disclosure.

Referring to FIG. 15B, in operation 1560, the AR device 1505 may detect a movement of the AR device 1505. For example, the AR device 1505 may detect the movement of the AR device 1505 through a head pose sensor (e.g., the head pose sensor 552 in FIG. 5) or a motion sensor.

In operation 1570, the AR device 1505 may determine whether the second GUI 1520 is located within the viewing area 1510, in response to an event that the movement is detected.

When the second GUI 1520 is located within the viewing area 1510, in operation 1580, the AR device 1505 may display a text (e.g., 1525) corresponding to a message through the display.

When the second GUI 1520 is not located within the viewing area 1510, in operation 1590, the AR device 1505 may output a voice corresponding to a message through a speaker.

FIG. 16 illustrates a UI for displaying a received message according to an embodiment of the disclosure.

Referring to FIG. 16, after a message thread is generated, a user device (e.g., the user device 620 in FIG. 6) may receive a message from a counterpart of another contact (e.g., a contact corresponding to a third avatar 1612) for which the message thread is not generated. To notify a user of a message received from the counterpart for which the message thread is not generated, an AR device (e.g., the AR device 610 of FIG. 6) may provide a graphic effect indicating a gesture of the third avatar 1612 included in a first GUI 1610 (e.g., the first GUI 910 of FIG. 9). For example, the AR device may provide a graphic effect indicating a gesture in which the third avatar 1612 raises a hand.

FIG. 17 illustrates a second GUI including a plurality of avatars in an AR according to an embodiment of the disclosure.

Referring to FIG. 17, while a second GUI 1720 (e.g., the second GUI 920 of FIG. 9) including a first avatar 1722 (e.g., the first avatar 922 in FIG. 9) and a second avatar 1721 (e.g., the second avatar 911 in FIG. 9) is displayed, an AR device (e.g., the AR device 610 of FIG. 6) may detect a user gesture of moving a third avatar 1712 among avatars 1711 and 1712 included in a first GUI 1710 (e.g., the first GUI 910 of FIG. 9) to the second GUI 1720. The user gesture of moving the third avatar 1712 to the second GUI 1720 may be the same as or similar to the user gesture described with reference to FIG. 9. For example, the AR device may detect, through a hand pose sensor (e.g., the hand pose sensor 551 of FIG. 5), a movement in which a user's finger 1755 moves the third avatar 1712 in a specified direction 1750 while grabbing the third avatar 1712 and then drops the third avatar 1712 on the second GUI 1720.

According to an embodiment of the disclosure, a user device connected to the AR device may simultaneously communicate with a counterpart of the second avatar 1721 and a counterpart of the third avatar 1712, in response to detecting that the third avatar 1712 is positioned at a location adjacent to the second GUI 1720. FIG. 17 illustrates an embodiment in which only the third avatar 1712 is added to the second GUI 1720, but the number of avatars added to the second GUI 1720 is not limited thereto.

According to an embodiment of the disclosure, as the third avatar 1712 is disposed at a location adjacent to the second GUI 1720, the AR device may provide a graphic effect such that the avatars 1712, 1721, and 1722 included in the second GUI 1720 express greeting each other.

FIG. 18 illustrates an operation of selecting one of a plurality of avatars disposed on a second GUI according to an embodiment of the disclosure.

Referring to FIG. 18, an AR device 1805 (e.g., the AR device 610 in FIG. 6) may select one of remaining avatars 1822 and 1823 disposed on a second GUI 1820 other than a first avatar 1821 corresponding to a user account of the AR device 1805 in an AR 1800, based on a gaze direction of a user 1810 wearing the AR device 1805. For example, when a message input is obtained while a gaze direction 1815 of the user 1810 points to the second avatar 1822, it may be indicated that the obtained message input is used for a counterpart of a contact corresponding to the second avatar 1822.

Although not illustrated in FIG. 18, according to other embodiments of the disclosure, the AR device 1805 may select the second avatar 1822 among the avatars 1822 and 1823, in response to obtaining a user voice for calling an identifier or name of the second avatar 1822, or detecting that a finger of the user 1810 points to the second avatar 1822.

FIG. 19 illustrates an operation of sharing content in an AR according to an embodiment of the disclosure.

Referring to FIG. 19, while a second GUI 1920 (e.g., the second GUI 1820 in FIG. 18) including a first avatar 1921 and a second avatar 1922 is displayed, an AR system may obtain a user input for sharing content in an AR. For example, the content may include at least one of an image, a video, a link, a map, another person's contact, music, a file, a voice message, or a schedule.

For example, in operation 1901, the AR system may detect a user gesture of sharing content 1910 output in the AR. For example, the user gesture may include a gesture of grabbing the content 1910 and dropping the content 1910 on the second GUI 1920 similar to the principle described with reference to FIG. 10A.

As another example, in operation 1902, the AR system may obtain a user input for sharing content 1935 output on a touch screen of a user device 1930 (e.g., the user device 620 in FIG. 6) in the AR. For example, the user input may include a swipe input facing in a specific direction (e.g., upward) on the touch screen.

FIG. 20 illustrates an interaction scenario in a second GUI according to an embodiment of the disclosure.

Referring to FIG. 20, it is assumed that a second GUI 2010 including a first avatar 2011 and a second avatar 2012 is displayed in an AR. Operation 2001 to operation 2003 are not implemented in order and may be performed independently.

Referring to FIG. 20, in operation 2001, an AR device (e.g., the AR device 610 in FIG. 6) may express a user's emotion through a first avatar 2011 corresponding to a user account. For example, the AR device may display a UI 2015 for selecting various gestures of the first avatar 2011, and may control the first avatar 2011 to express a gesture selected in the UI 2015.

In operation 2002, the AR device may display a UI 2025 indicating that a voice message is being output while the voice message received from a counterpart of a contact corresponding to the second avatar 2012 is being output.
